Clinical photodynamic therapy (PDT) has existed for over 30 years, and its scientific basis has been known and investigated for well over 100 years. The scientific foundation of PDT is solid and its application to cancer treatment for many common neoplastic lesions has been the subject of a huge number of clinical trials and observational studies. Yet its acceptance by many clinicians has suffe...

Appending anthracene units to [(bpy)2Ru(dpp)](2+) results in Ru(II) agents that exhibit dynamic photoreactivity towards DNA and protein. [(Anthbpy)(bpy)Ru(dpp)](2+) and [(Anthbpy)2Ru(dpp)](2+) are the first metal-organic Ru(II) agent with dpp ligands shown to photomodify DNA in the presence or absence of oxygen, while also binding protein in an oxygen-dependent manner.

A library of glycosylated porphyrins (glycoporphyrins) was prepared and the compounds were evaluated for their photodynamic therapy (PDT) activity against the oesophageal squamous-cell carcinoma cell line OE21 in vitro. A synthetic methodology was developed to allow incorporation of biologically active carbohydrates, including the histo-blood-group antigen trisaccharide Lewis(X), onto the porph...

BACKGROUND AND OBJECTIVE To describe the introduction and use of intense pulsed light (IPL) to treat vascular and pigmented lesions comprising photorejuvenation and its use in photodynamic therapy. METHODS Review of the medical literature and the authors' experience with IPL. RESULTS AND CONCLUSIONS IPL is an excellent treatment modality for vascular and pigmented manifestations of photoagi...

In this work, the synthesis and the nonlinear absorption and population dynamics investigation of a series of zinc phthalocyanines (ZnPcs) dissolved in chloroform are reported. In order to determine the relevant spectroscopic parameters, such as absorption cross-sections of singlet and triplet excited states, fluorescence relaxation times, intersystem crossing, radiative decay and internal conv...

Introduction: Vitiligo is a specific, common, often heritable acquired disorder characterized by well-circumscribed milky white cutaneous macules and patches devoid of identifiable melanocyte. Treatment vitiligo, though quite frustrating, includes repigmentation therapies like Topical glucocorticoids, calcipotrieinene, PUVA (Psoralen + Ultraviolet Light A). The combination calcipotriol proves e...
